This year has seen several international, national, and local issues relating to global warming.
Organizationally, the IPCC or the Intergovernmental Panel on Climate Change might be considered the lead agency on issues of global warming. The IPCC is a group of thousands of climate scientists from around the world. The fifth pentennial assessment report states: “to avoid dangerous interference with the climate system, we need to move away from business as usual. Simply to hold the temperature rise to 2 degrees [Celsius] will require reductions of green house gases from 40 to 70 per cent compared with 2010 by mid-century, and to near-zero by the end of this century.”
Whereas the IPCC is the scientific wing of the UN, the UNFCCC or the United Nations Framework on Climate Change is more of a political policy wing. In their meeting in Lima Peru this year they concluded that it is increasingly difficult to prevent the temperature of the planet’s atmosphere from rising by 3.6 degrees Fahrenheit. According to a large body of scientific research, that is the tipping point at which the world will be locked into a near-term future of drought, food and water shortages, melting ice sheets, shrinking glaciers, rising sea levels and widespread flooding—events that could harm the world’s population and economy.
After months of negotiations, President Obama and President Xi Jinping in November affirmed the importance of strengthening bilateral cooperation on climate change and will work together to adopt a protocol on climate change. They are committed to reaching an ambitious 2015 agreement that reflects the principle of common but differentiated responsibilities and respective capabilities, in light of different national circumstances.
In June President Obama, through the Environmental Protection Agency, has promulgated rules for power plants to reduce carbon emissions by 30 per cent by 2030. This is the first time that the EPA has taken steps to regulate Carbon Dioxide as a pollutant, an action begun in 2007 by President Bush, but delayed by court battles meant to block the regulations.
Construction of the Keystone XL pipeline remains stalled. This pipeline, if completed, will move oil produced by strip mining the Athabasca tar sands in Alberta Canada. The line will terminate after traversing almost 1200 miles at refineries on the Gulf coast. It’s approval is questionable as this will exacerbate global warming by providing an international market for more carbon emissions.
The draft Environmental Impact Statement for the proposed Plains and Clean Line has been released. Basically the EIS determined that there are no adverse environmental or socioeconomic effects of the transmission line. The power line will move 3,500 MegaWatts of wind generated electricity from the panhandle of Oklahoma, across Arkansas to Memphis.
Entergy has recently purchased a gas turbine fired electrical power plant near El Dorado. With a capacity of 1980 MegaWatts, this may signal the intention to close the older less efficient coal fired White bluff plant.
